Correct. All three Dells currently working here are of the time period
just before the decision to use these chipsets. I've also been
checking the motherboards I've got roosting here. So far, one is
listed as not having one, I'll know more soon.

Of course luckily one of the listed chipsets is the Ali family of add
ins so that should work. I can easily find one of those. (Add in
boards of course.)

And one of my occasional Linux users happens to be an SiS based
system, who happens to be one of the first generation of targets for
the families of coreboot.
